1105710 - [E10S][Firefox36] Moz Repl (Extension) not working

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[julio.dcs]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141113143407

Steps to reproduce:

Used a perl script using WWW::Mechanize::Firefox

The script logs in a site and starts downloading some files.

It works with current version 33.1.1



Actual results:

Without an electrolysisless window, the process starts, a new tab is created, logs in to the site, follows some links, etc. But It seems to fail downloading a file:

I get this message:

MozRepl::RemoteObject: NS_ERROR_XPC_NOT_ENOUGH_ARGS: Not enough arguments [nsIWebBrowserPersist.saveURI] at whatever.pl line 448.

$mech->save_url($download , $exefile);

Probably, not a problem of firefox/addon itself, but the mechanize package that should be updated.

With an electrolysis window things get a bit worse :/

First I get this message:

MozRepl::RemoteObject: TypeError: invalid 'in' operand obj at whatever.pl line 374
    $mech = WWW::Mechanize::Firefox->new(repl => "localhost:$port")

If I retry, then I get:
    MozRepl::RemoteObject: TypeError: this.docShell is null at D:/Perl/site/lib/Firefox/Application/API40.pm line 131.

At this point, all tabs that were opened before the script launch, are freezed. They cannot be even closed.





Expected results:

Electolysis case should work the same as non-electrolysis case.

This is a bug in WWW::Mechanize::Firefox, and not in Firefox. You should file it with the CPAN maintainer of the module.
